The Structure of Drawings The following example creates and inserts a rectangle in a drawing document: Dim Doc As Object Dim Page As Object Dim RectangleShape As Object Dim Point As New com.sun.star.awt.Point Dim Size As New com.sun.star.awt.Size Doc = ThisComponent Page = Doc.DrawPages(0) Point.x = 1000 Point.y = 1000 Size.Width = 10000 Size.Height = 10000 RectangleShape = Doc.createInstance("com.sun.star.drawing.RectangleShape") RectangleShape.Size = Size RectangleShape.Position = Point Page.add(RectangleShape) The Point and Size structures with the point of origin (left hand corner) and the size of the drawing object are then initialized. The lengths are specified in hundredths of a millimeter. The program code then uses the Doc.createInstance call to create the rectangle drawing object as specified by the com.sun.star.drawing.RectangleShape service. At the end, the drawing object is assigned to a page using a Page.add call. Fill Properties This section describes four services and in each instance the sample program code uses a rectangle shape element that combines several types of formatting. Fill properties are combined in the com.sun.star.drawing.FillProperties service. OpenOffice.org recognizes four main types of formatting for a fill area. The simplest variant is a single-color fill. The options for defining color gradients and hatches let you create other colors into play. The fourth variant is the option of projecting existing graphics into the fill area. The fill mode of a drawing object is defined using the FillStyle property. The permissible values are defined in com.sun.star.drawing.FillStyle. Single Color Fills The main property for single-color fills is: FillColor (Long) fill color of area To use the fill mode, you must the FillStyle property to the SOLID fill mode. The following example creates a rectangle shape and fills it with red (RGB value 255, 0, 0): Dim Doc As Object Dim Page As Object Dim RectangleShape As Object Dim Point As New com.sun.star.awt.Point Dim Size As New com.sun.star.awt.Size Point.x = 1000 Point.y = 1000 Size.Width = 10000 Size.Height = 10000 Doc = ThisComponent Page = Doc.DrawPages(0) RectangleShape = Doc.createInstance("com.sun.star.drawing.RectangleShape") RectangleShape.Size = Size 114 OpenOffice.org 3.2 BASIC Guide · March 2010
RectangleShape.Position = Point RectangleShape.FillStyle = com.sun.star.drawing.FillStyle.SOLID RectangleShape.FillColor = RGB(255,0,0) Page.add(RectangleShape) Color Gradient If you set the FillStyle property to GRADIENT, you can apply a color gradient to any fill area of a OpenOffice.org document. The Structure of Drawings If you want to apply a predefined color gradient, you can assign the associated name of the FillTransparenceGradientName property. To define your own color gradient, you need to complete a com.sun.star.awt.Gradient structure to assign the FillGradient property. This property provides the following options: Style (Enum) type of gradient, for example, linear or radial (default values in accordance with com.sun.star.awt.GradientStyle) StartColor (Long) start color of color gradient EndColor (Long) end color of color gradient Angle (Short) angle of color gradient in tenths of a degree XOffset (Short) X-coordinate at which the color gradient starts, specified in hundredths of a millimeter YOffset (Short) Y-coordinate at which the color gradient begins, specified in hundredths of a millimeter StartIntensity (Short) intensity of StartColor as a percentage (in OpenOffice.org Basic, you can also specify values higher than 100 percent) EndIntensity (Short) intensity of EndColor as a percentage (in OpenOffice.org Basic, you can also specify values higher than 100 percent) StepCount (Short) number of color graduations which OpenOffice.org is to calculate for the gradients The following example demonstrates the use of color gradients with the aid of the com.sun.star.awt.Gradient structure: Dim Doc As Object Dim Page As Object Dim RectangleShape As Object Dim Point As New com.sun.star.awt.Point Dim Size As New com.sun.star.awt.Size Dim Gradient As New com.sun.star.awt.Gradient Point.x = 1000 Point.y = 1000 Size.Width = 10000 Size.Height = 10000 Doc = ThisComponent Page = Doc.DrawPages(0) RectangleShape = Doc.createInstance("com.sun.star.drawing.RectangleShape") RectangleShape.Size = Size RectangleShape.Position = Point Chapter 8 · Drawings and Presentations 115
